Clip-on Mechanical Fracture Gauges Model 3541

---

.

Special configurations are available to meet ASTM E399 requirements for fracture toughness (please consult the factory for these configurations). In addition, the modified slot design complies with E1820 testing, providing greater stability and improved accuracy in crack tip measurements.

.

Clip-on gauges are used for a variety of fracture mechanics tests, including compact tension, bend specimens, disc-shaped specimens, and other sample geometries in accordance with ASTM and other standardized testing methods.

 .

Clip-on gauges can be used directly on test specimens where knife edges are integral to the specimen, or alternatively with knife edges mounted onto the specimen. Model 3541 extensometers are strain-gage devices compatible with any electronics designed for strain gauge transducers. They are frequently connected to a testing machine controller.

.

Signal conditioning electronics for the extensometer are typically included with the testing machine controller or can often be added. In such cases, the extensometer is supplied with the appropriate connector and wiring for direct integration with the electronics.

 

For systems lacking the necessary electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders, or other equipment.
